' Patented Sept. 27, 1932 UNITED STATES PATENT 1 oFi-"Ica LEWIS D. BARNETT, OF COLUMBUS, OHIO, ASSIGNOR TO THE BUCKEYE BLOWER GOM- PANY, OF COLUMBUS, OHIO A CORPORATION OF OHIO DOUBLE RADIATOR WITH MEANS'OF SIOIN' ON RADIATOR S Application filed August 15, 1981. Serial 110155732 18.

My invention relates to heating and ventilating apparatus. 7

It is the object of my inventlon to provide a novel form of radiation comprising two '3 radiators having a common header at one end and independent headers at the other, preferably so arranged that one header Wlll slide upon the other, and independent control valves for the respective radiators. i

It is a further object of my invention to provide means on said radiators for guiding air thereover, first over one radiator and thence over the other radiator forming continuous, transverse air passageways 1rrespec- '16 tive of the independent movement of the radiators and their guiding means due (11f: ferent rates of expanslon and contraction of the sections of the radiator which may be subject to different temperatures at the same 20 time. A

Referring to the draw ngs: Figure 1 is a front elevation of the heatmg and ventilating unit, partially in section, with the cover partly removed from the front 25 of the radiator and with one of the fan casings partly broken away to show the arrangement of the fan;

Figure 2 is a section on the hue 22 of Pi re 1; v

igure 3 is a perspectlve' of the radlator with the header partially broken away showin the common header for the two radiators; %igure 4 is a similar view showing'the arrangement of the independent headers which are arranged to slide one on the other Referring to the drawings in detail, 1 mdicates the front of a casin having the bot tom 2, a recirculation grill 3 1n the front 1 and 40 side walls 4. and 51. These side walls have porting the radiators. The back of the casing 8 is provided with the fresh air inlet opening 9 controlled by the damper 10. Air passes upwardl through the fan 11 in the casin 12 and ischarges through the opening 13 into the chamber 14 and thence passes over the radiators 15 and 16 out the air exit opening 17 in the top 18.

plurality of transversely-arranged vertical interiorly disposed brackets 6 and 7 for sup-' support. By arranging the ra Each of these radiators is provided with a" plates 19 havingturned-over, angular, U- shaped ends 20 abutting against one another to form vertical air passageways 21 through which airflows over the pipes 22 and 23 re I spectively of the radiators 15 and 16.

These passageways are substantially in bus with one another although the vertical plates 21 are not continuous but independent sets of these plates are mounted on each set of I the pipes 22 and 23. These pipes are mounted at one of their ends in acommon header. w 24 having independent steam chambers 25- and 26 supplied by the pipes 27 and 28. The header is divided by a partition- 29 to form the steam chambers 25 and 26. In-' dependently controlled valves 30 and 31 control the pipes 27 and 28. Independent exit pipes 32 and 33 are provided for connection to the independent headers 34and 35. The top header 34 is adapted to slide upon the bottom "header and the bottom header is mounted upon a leg 36 which enables it to slide asit expands and contracts upon the bracket 7 on the inside of the casing.

Referring to the passage of the air throu h the system, the fresh air enters through t e opening 9, passes upwardly under the influence of the fan 11, discharges through the opening 13 and into the expansion chamber 14 and thence over the radiator pipes 22 and 18a 23 between the plates 19 through the passageways 21;and out the outlet opening 17.

In operation, as the steam is independently cut on and ofi in 'the two radiators the pipes 22 and 23 expand and contract indegag pendently depending upon their tempera- I ture. Y Heretofore, this has resulted, when the pipes were mounted in common headers, in a loosening of the pipes in the headers making it difficult to keep tight steam connections. .Furthermore, it has been difficult to employ independent controls because of this result. 7

On the other hand, independent radiators not connected into a common header make it diflicult to provide proper alignment and iators with a common header at one end and supporting headers slidably mounted, a single support me at either end is sufficient for supporting the entire radiator system. 7

. The fans 11 are operated by the motor 110;

. from the armature shaft 116. Thedamper may be controlled either automatically or by hand through the button 37.,

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to vary 1o ing conditions'and uses.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

'1. In combination, in a radiator, of a com-' 'mon header having separate supply cham bers, radiator pipes connected to said chambers, independent radiating fins mounted on said pipes forming with one another pas-i for continuous passage of' air therethrough,

irrespective of the independent movement of said pipes.

3. In combination, in a radiator, of a common header having separate supply chambers,-a set of radiator pipes connected to each chamber, radiating fins mounted on each set of said pipes having passageways there- 86 between, and independent headers at the other ends of said pipes.

4. In combination, in a radiator, of a com mon header having .separate supply chambers, a set of radiator pipes connected to each chamber, radiating fins mounted on each of said fins and passageways being so'arran'ged that-they are in substantial alignment for continuous passage of air therethrough irrespective of the independent movement of said pipes, and independent header's at the other ends of said pipes. 5. In combination, in a'radiator, of a com-' mon header having separate supply chambers, aset of radiatorpipes connected to each chamber, radiating fins mounted on each set of said pipes having passageways there between, and independent headers at the other ends of said pipes slidably engaglng one another. I

- 6. In combination, in a radiator, of a common header having separate supply chambers, a set of radiator to each chamber, radiating ns mounted on eachset of said pipes having passageways therebetw een, said finjs and passageways being so arranged that they are in substantial alignment for continuous passage of air therethrough irrespective of the independent 65 movement of said pipes, and independent said pipes havingpassageways therebetween,

ipes connected headers at the other ends of said pipes slidablyengaging one another.

supported on said casing in the other end thereof.

'8. In a heating and ventilating unit, a casing having an air inlet opening at the bottom and an airoutlet opening at the top, dual radiators mounted therein therebetween, a common header supported on said casing for said dual radiators at one end thereof, and: independent headers for said radiators supported on said casing in the other end thereof, said independent headers being slidably mounted one upon the other and having a common support.

9. In combination, in a heating and ventilating unit, of a casing, a fan, an air inlet and an air outlet opening, a plurality of radiators, each having an independent set of radiating fins comprising vertically-disposed air chambers in alignment with one another in the direction of the passage of air through said openings actuated by said fan, a common header for said radiators at one end and independent headers at the other.

10. In combination, in a heating and ventilating unit, of a casing, a fan, an air inlet and an air outlet opening, a plurality of radiators, each having an independent set of radiating fins comprising vertically-disposed air chambers in alignment with one another in the direction of the passage of air through said openings actuated by said fan, a common header for said radiators at one end and independent headers at the other, and means for supporting said common header at one end on the casing without movement, and means for supporting said independent headers on the casing at the other end of the radiators whereby one of said independent headers is supported without movement and the other is slidably mounted thereon.

11. Anew article of manufacture for use as a radiator comprising a common header having separate chambers at one end, radiator pipes connected thereto and independent headers at the other end, and separate sets of transverse fins on each pipe forming with one another substantially continuous air passageways over both pipes while permitting independent movement of each pipe with its own set of transverse fins.

. 12. A new article of manufacture for use as a radiator comprising a common header having separate chambers at one end, radiator pipes connected thereto, independent headers at the other end, said independent headers resting slidably one on the other, and 130 separatesets of transverse fins on each pipe forming with one another substantially continuous air passageways over both pipes while permitting independent movement of each pipe with its own set of transverse fins.

13. A new article of manufacture for use as a radiator comprising a common header having separate chambers at one end, radiator pipes connected thereto, independent headers at the other end, said independent headers resting slidably one on the other, a common means for supporting said respective headers, and separate sets of transverse fins on each pipe forming with one another substantially continuous air passageways over both pipes while permitting independent movement of each pipe with its own set of transverse fins.

In testimony whereof, I afiix my signature.
